This one about whether designers are crazy because the OP didn't understand why designers would care about minute details in their work. It is because attention to detail creates superlative work. It is similar to why premature optimization isn't
necessarily bad for engineers.

No, designers aren't crazy. You just don't understand a very fundamental concept of design. It even applies to engineering. It's okay—many people have the same frustrations as you do.
But those who care about the details achieve truly high quality results overall. It extends to all areas of the design, not just to the parts you can't see.
In the movie "Who Framed Roger Rabbit," there's a scene in a dark room where Roger Rabbit (an animated character) flies across the room, knocks a hanging lamp around, and the lighting becomes so dynamic that all the shadows move around including the animated character's shadow. Here's the scene in question: http://www.youtube.com/watch?v=_EUPwsD64GI
This was such a small detail that it would have been forgivable if the animators had left it out entirely: if they had not moved the lamp, kept the shadow steady, no one would have really noticed the difference. It would have been 100 times easier to animate and the effect wouldn't really have been that different.
But they did it anyway. The term was later coined, and "bump the lamp" is used throughout Disney (and probably other organizations) to mean something akin to "go the extra mile"—but I see it as having a special significance to design.
You're right, most people won't notice. By that logic, you could cut corners a lot of other places too. You could be lax about button colors matching exactly, or per-pixel sharpness on the map and buttons. No one would probably notice.
But if you go for every detail like it was the most important detail, you have the possibility of reaching a level of design quality that is superlative, and some people will notice. Others will not notice directly, but will see that the piece exudes style and quality subconsciously, due to the attention to small details. If you carry this into other areas of your work—programming, customer service, market strategy, marketing, and more—then you have a chance to create something of true quality.
If you don't pay attention to detail at that level, well, you might have the chance to actually get something done. Yes, it's a balance, like everything else. But you have to know that it won't be quite as good, and understand that yes, you are sacrificing something, even if you can't see it.
